BENOIT LACROIX, OF CHAZELLES-SUR-LYON, FRANCE.

BRUSHING-MACHINE.

Application filed May 6, 1913.

T all whom it may concern:

Be it known that I, BENOIT LAC-ROIX, a citizen of the Republic of France, residing at Chazelles-sur-Lyon, Loire, in the Republic of France, have invented 'new and useful Improvements in Brushing-hlaohines, of which the following is a. specification.

This invention relates to improvements in brushing machines and refers to that class in which rotary brushes and conveyers comprising bands and rollers are provided for conveying the articles to and away from the brush.

The object of this invention is to provide an improved machine of the specified type.

The automatic brushing of felts is accomplished in the various directions necessary to obtain perfect results.

The improved machine operates on the whole surface of the objects to be brushed, without leaving any place to be gone over separately afterward inany manner whatsoever. This machine is composed essentially, -as is shown in the annexed drawing, of several brushes F, for example six, placed in sectors on a cylindrical surface, similar to those represented in the drawing, revolving on the axle M, capable of being regulated above a stationary, metal, concentric, lower trough G.

The objects to be brushedare folded in the front of the machine on a moving carpet T and are conducted between the two rollers A and B by means of another roller which grips them and brings them beneath the brush. The brush then drags them along by its rotary movement, and thus accomplishes the actionof brushing while they are being passed between the bristles of the brush and the exterior surface of the metal lower trough G. The articles when brushed are thrown at a tangent outside the trough. A protector S stops them, and causes them to fall on a moving carpet T After the firstbrush-i the objects are'taken up and again place on the front table where they are unfolded in order to be folded-in a different manner, after which they are inserted again between the rollers to receive a second brushing, They are passed through the machine, as many times as is necessary, until' the final result is obtained. In the case of a hat crown, folded in two and crossed, the operation is carried outifour times for the nap on the outer surface, and as many times for that on the inner surface.

same shaft which is supplied with a toothed pinion 1, brings into action, by means'of a Galle chain 2, an intermediate shaft 3, supported at U by the frame of the machine K. This shaft drives, through a pinion 4 and Galle chain 5, a pump P for supplying the boiling liquid necessary for the brushing. The rolling carpets T and T, in the front and rear, are put in motion by gearing and 7 from the main shaft M. The shaft M is supported by an exterior block L placed on a chair separated-from the machine, and by two'blocks N, N, resting on the frame. These three blocks can be fixed vertically or horizontally by means of suitable known devices, permitting'the distance between the bristles of the brushes on the cylindrical surface of the conducting roller and the arched surface of the lower trough to be gaged as required. The axles of the feed rollei's'can alsobe regulated, as they rest in guides, Q, Q1

The frame is made of two cast-iron supports K, K, including the strutted foot-supports and the brackets on which rest the tables or rolling-mats behind and in front of the machine. A straight bore V, V, allows of the adjustment in a verticaldirection. The two half-frames K, K, hold between them the lower trough, which is fixed against them, and at the same time acts as a strut for the central portion. The other struts E unite the brackets and also the foot-supports. Between the two walls and under the trough G is placed the tank R, where a. water-pipe 8 maintains the liquid at the required temperature. This tank is supplied with wheels X, X, for the purpose of removing it from its place when it is required to clean or repair the same. ()n the suction side of the pipe there is a vertical compartment Y which acts as a filter. The clear liquid, drawn up by the pump, is driven back into the tube C, conveniently placedand supported by the straps I) attached to the frame by means of apipe; 9 connected 'to the delivery end of the pump P. As the result of pressure, the liquid is projected on to the felts, from whence it is diverted at D, after which it crosses an inclined grating G which prevents the passage of the nap which has been extracted. The Water then falls again into the tank R.

The liquid carried away by the objects brushed drainsoff on to the table or rollingmat at the back. A zinc return way Z, placed beneath, conducts it back into the tank vvhere it is again heated by means of the water-pipe.

A disengaged clutclrD placed Within reach of the workman, who isin attendance at the front table, facilitates the stopping or the bringi' g into operation of the machine as required. The Galle chains and their cogged Wheels are capable of being regulated and stretched, in such a way as to compensate the movements of the'axles M, A and B. The brackets which support the mats are also supplied With stretchers for same.

What I claim and desire to secure by Letters Patent of the United States is 1. 'In a brushing machine, the combination of a conveyor, conveying rollers, a rotary brushing element comprising segmental brushes, a stationary trough under said brushing element against which the article to be brushed is pressed during the brushing action, liquid spraying me'ans disposed between said conveying rollers and said rotary brush, a protector for stopping the finished article ejected by the said brush and a conveyer for receiving the finished article.

2. In a brushing machine, the combination of a conveyer, conveying rollers, a rotary brushing element comprising segmental brushes, a stationary trough under said brushing element against which the article to be brushed ispres'sed during the brushing action, liquid spraying means disposed between said conveying rollers and said rotary brush, a protector for stopping the finished article ejected by the said brush, a conveyer for receiving the finished article, and means for heating the liquid supplied to said spraying means.

3. In a brushing machine, the combination of a conveyer, conveying rollers, a rotary brushing element comprising segmental brushes, a stationary trough under said brushing element against which the article to be brushed is pressed during the brushing action, liquid spraying means disposed be-' tween said conveying rollers and said rotary brush, a tank disposed below said rotary brushing element for containing a liquid, means for heating said liquid and means for distributing said. liquid to said spraying means.

4. In a brushing machine the combination of a conveyer, conveying rollers, a rotary brushing element comprising segmental brushes, a stationary trough under said brushing element against which the article to be brushed is pressed during the brushing action, liquid spraying means disposed between said conveying rollers and said rotary brush, a tank disposed below said rotary brushing element for containing a liquid, means for heating said liquid, means for dis tributing said liquid to said spraying means and a return way for conveving'the surplus liquid back to said tank.

In testimony whereof I have'signed my name to this specification in the presence of two subscribing witnesses.

BENOIT LACROIX.
